i have hp PM_A_HPC_S_MV_MB_V1 MOTHERBOARD.
the 3.3/5v voltage regulator is working.
i do not have the 5v on usb.
following the schematic i notice that from ITE8502 ,EC_USB_PWR_EN goes to usb chip APL3510 EN pin directly which suppost to be 3.3v, i get 0.05v and then goes to 0 and then back to 0.05v.
Can i give 3.3v from some other place instead of changing SIO ic!
Thanks
